A cooling system, which includes a compressor for compressing the refrigerant by operation of a motor, a condenser, an expansion means, and an evaporator, comprises a motor cooling device for cooling down the motor by making some of the refrigerant passed the condenser flow to the compressor according to temperature of the motor, and therefore the heat of high temperature generated from the motor in the compressor during the operation of the compressor which is used in the cooling system can be cooled down efficiently.
